SB800: Hide unused gpp ports
Add configure option SB_GPP_UNHIDE_PORTS for mainboard to hide/unhide the unused sb800 gpp ports. Certain gpp port should be hidden, if no device was detected and hotplug feature is disabled for such port. Hidden unused ports makes lspci -vvv get more accurate information under Linux. Test on avalue/eax-785e mainboard.
